Post-leave burnout recovery, week 2:
Lots of mixed feelings in returning to work. I really missed my team and my job. Work and the work schedule are each somewhat helpful for recovery. 1:1s with reports and partnerships are a strong highlight of my week!
Motivation while recovering from the tail end of burnout is hard for some types of work as a manager. Burnout makes motivation hard as it is, and lack of context on what's going on makes that harder, and both of those exacerba…

White House deputy chief of staff and Homeland Security adviser
Stephen Miller posted an ominous, captionless threat after democratic socialist Zohran Mamdani won the New York City mayoral election on Tuesday night. 
“Almost 50 percent of New Yorkers live in households with at least one immigrant,”
read the screenshot he posted from NYC.gov titled “Family Household Types by Immigration Status”
“Over one million children, equaling 62 percent of the children in New York …

Stephen Miller Posts Cryptic Threat After Zohran Mamdani’s Win
The Trump administration is already vowing to go after New York following Zohran’s election win.

CAD model of the #tricycle subframe. The chain ring is very nearly as big as the front wheel (80 teeth!). It drives an epicyclic gearbox mounted in the nose of the vehicle, which also has a disc brake. The epicyclic will drive a secondary chain via a sprocket mounted to the left hand spoke flange, but this is not yet shown. There will be no ratchet on the secondary chain, so the disk brake on the…

OK, maybe I went too nerdy 🤓 on this one? 🤣

The latest 3blue1brown video on Burnside's lemma made me realise that the HoTT/concrete group version of the following fact:
Given a G-set X and a set Y, the set of invariant functions X − Y under the action of G is equivalent to the set of functions X/G − Y.
is just the "dependent currying" isomorphism
((s : BG) − X(s) − Y) ≃ (((s : BG) × X(s)) − Y)
since Π-types give invariants and Σ-types give orbits.

Continual Neural Topic Model
In continual learning, our aim is to learn a new task without forgetting what was learned previously. In topic models, this translates to learning new topic models without forgetting previously learned topics. Previous work either considered Dynamic Topic Models (DTMs), which learn the evolution of topics based on the entire training corpus at once, or Online Topic Models, which are updated continuously based on new data but do not have long-term memory. To fill this gap, we propose the Continu…

Zwei Veranstaltungstipps für Berlin:
1) Von Filmhistoriker und -theoretiker Tobias Ebbrecht-Hartmann ist unlängst das Buch "Gewalt als Bild. Die Bilder vom 7. Oktober im Spiegel der visuellen Erinnerung an die Shoah" erschienen (Neofelis Verlag). Kommenden Sonntag gibt es dazu eine Diskussion im Jüdischen Museum Berlin mit Annette Vowinckel.

Gewalt als Bild. Die Bilder vom 7. Oktober im Spiegel der visuellen Erinnerung an die Shoah

Already the spirit of our schooling is permeated with the feeling that
every subject, every topic, every fact, every professed truth must be
submitted to a certain publicity and impartiality. All proffered
samples of learning must go to the same assay-room and be subjected to
common tests. It is the essence of all dogmatic faiths to hold that
any such "show-down" is sacrilegious and perverse. The characteristic
of religion, from their point of view,…
